Answer:
Me, I just learned it, I can help
Step-by-step explanation:
Formula:
ax^2 + bx + c
Answer:
your answer is a complex number making your question wrong
Step-by-step explanation:
First z²+z+20=0, just to make it a quadratic equation, so we can use the quadratric formula:
x=( -b±√b²-4ac)/2a
so to find a b and c we compare
YOUR QUESTION SHOULD BE Z² +Z-20=O.
Answer:

Step-by-step explanation:
1. Well, when it comes to triangles. Mainly Pythagorean Triple, right triangles whose sides are 3,4,5 or 5,11,12
2. Keeping in mind this a Pythagorean Triple, then x=5
3. Then we can write it as Compound Inequality by combining the Statements for an Inequality of Triangle:
We can write it as

Or we can do:

and:

4. Writing in terms of x:

Applying multiplication of functions, the total number of seats in the auditorium is given by:
h(x) = 80x² + 560x.
<h3>How polynomial functions are multiplied?</h3>
They are multiplied applying the distributive property, that is, all the terms are multiplied and then the common terms are added.
In this problem, the functions are given as follows:
Then the multiplication is:
h(x) = f(x)g(x) = 80x(x + 7) = 80x² + 560x.
